I had a stereo shop install a dvd monitor into my 2005 Chevy Suburban. They removed the rear climate control system. My dvd system no longer works and I want to put the climate control system back. However, I need to see what kind of clips or bolts that I need to secure the climate control back in place. Thank you Jody2x2reme@cox.net
The rear ac controls have the snaps built in onto the unit. When they installed the overhead dvd they prolly stuffed the ac controls up in the headliner. You will have to replace entire headliner to reinstall the panel correctly. Be cheaper to repair dvd unit, and reinstall over the hole. The front controls in that car are the master controls anyway, you dont have to have the rear ones to make the rear ac work.

You didn't state a year. But all overhead parts that I have pulled, just pop out. Held in with clips. On some older models you have to open doors and find the screws to take the whole console down. Screws out and it hinges down and out.
Could be the controller or a faulty blend door. The blend doors direct air thru the heater core and evaporator along with the vents. The controller uses electric motors to change the direction of air flow.
Before removing the stereo you need to ensure that the battery's grounding cable is disconnected from the negative lead. Most BMW models have the battery housed under the hood while others (a relative few) store the battery on the left side of the vehicle in the trunk. Use a 10 mm wrench to loosen the bolt holding the clamp of the grounding cable around the negative lead.
Use a trim pry tool to remove the vent housing above the stereo. The vents can be removed to allow access to the stereo or removed completely. Once the perimeter of the vent housing is loose from the dash, you can feed the wiring that connects to the hazard light button through the front of the vents. With the hazard switch pushed forward, simply disconnect the power supply to completely free the vent assembly.
The climate control group at the bottom of the stereo also needs to be removed to access the stereo. The climate control housing can be removed by hand. Grab the climate control at the bottom and the top. Pry from the bottom and remove. The climate controls do not need to be removed completely. When it is free from the dash there will be enough slack in the wiring to allow you to place it aside to access the stereo.
There are two screws that hold the factory stereo in its dock. Those screws, located on either side of the stereo facing upward, can be removed using Phillips-head screwdriver. Once the screws are removed, the deck slides forward to allow access to the wiring at the rear of the stereo. The wire groups at the rear need to be removed and can be done so in any order. The four wiring groups connect to the antenna, the amplifier, the speakers, and the power supply (the battery).
If you plan to install an aftermarket stereo, most will be compatible with BMW wiring. If not, you can connect the wiring groups to a wiring harness adapter before connecting to the new unit.
Make sure you have the anti-theft codes for the audio and the navigation system, and then write down the audio presets.
Disconnect the negative cable from the battery.
From under the hood, disconnect the heater valve cable from the heater valve. Turn the heater valve arm to the fully opened position.
When the engine is cool, drain the engine coolant from the radiator.
Disconnect the inlet heater hose and the outlet heater hose from the heater core.
Remove the mounting nut from the heater unit. Take care not to damage or bend the fuel lines, the brake lines, and related parts.
Remove the dashboard.
Remove the evaporator.
Remove the mounting bolts and remove the heater unit.
Front heater unit
Remove the self-tapping screws and the clamp.
Carefully pull out the heater core so you don't bend the inlet and outlet pipes.
Front heater core
Using care, install the heater core to the heater unit and secure.
Using care, install the heater unit and tighten mounting nuts and bolts to 7 ft-lb (10 Nm).
Install the evaporator.
Install the dashboard.
Connect the inlet heater hose and the outlet heater hose to the heater core.
Connect the heater valve cable to the heater valve.
Refill the cooling system with engine coolant.
Adjust the heater valve cable.
Make sure that there is no coolant leakage.
Make sure that there is no air leakage.
Connect the negative battery cable.
Perform the power window control unit resetting procedure.
Enter the anti-theft codes for the audio and the navigation system, and then enter the audio presets.
RearTo Remove: NOTE: The rear blower motor, the rear heater core, the blower screen, the rear blower resistor (heating/air conditioning system) and the rear power transistor (climate control system), the rear air mix control motor (climate control system) , the rear mode control motor and the rear expansion valve can be replaced without removing the rear heater-A/C unit.
Remove the self-tapping screws and the clamp, and then remove the bolts and the rear evaporator lines with the rear expansion valve. If necessary, remove the rear expansion valve. Use a second wrench to hold the other fitting on the valve so the rear evaporator lines won't twist. Leave the first fitting loosely connected so you can use it to hold the valve while you loosen the second fitting.
Remove the rear heater hoses.
If necessary, remove the rear blower motor, the rear heater core, the blower screen, the rear blower resistor (heating/air conditioning system), the rear power transistor (climate control system), the rear air mix control motor and the rear mode control motor.
Remove the self-tapping screws and the lower housing.
Remove the self-tapping screws, and carefully separate the left upper housing from the right upper housing. Remove the rear heater core.
Rear evaporator assembly
Replace the rear heater core.
Attach the heater hoses.
Make sure no air is leaking from the left upper housing and the right upper housing fitting and from the upper housings and the lower housing fitting.
Before reassembly, make sure that the rear air mix control linkage and door move smoothly without binding.
Before reassembly, make sure that the rear mode control linkage and door move smoothly without binding.
Reassemble the housing.
After reassembly, make sure the rear air mix control motor runs smoothly.
After reassembly, make sure the rear mode control motor runs smoothly.
Refill the cooling system and make sure that there is no coolant leakage.
if its the computer climate controlled series then it might be the the vents. what happenes some times is the vent wont switch over from hot to cold or vise-versa. i had the same problem but reversed, no heat in front and it worked up to the last time i had switched it from hot to cold.
give it a shot, best of luck
Tools required: Phillips screwdriver, small flatblade screwdriver, rachet with 6 inch extension & 10mm socket.
1. Remove negative battery terminal (for stray voltage & airbags.)
2. Remove gear shift trim
3. Remove cable attached to lighter socket.
4. Remove center climate control knob and screw beneath it.
5. Gently pry both bottom corners of climate control face (up then towards the rear) until clear of lock.
6. Pull entire climate control console rearward until clips release. Leave all wiring attached.
7. Remove 4 bolts under radio (10mm.)
8. Gently pry between dash and AC ducting panel (both sides) and pull out.
9. 4 clip hold radio to ducting panel, gently pry while pulling radio out the back.
The rest should be easy...
9. 4 clips hols radio to
I had the same problem on my 2004 GMC Yukon XL.
Still under warranty the shop was able to reprogram the climate control system and tell what was wrong rather quickly with a OBD computer.
That’s when they found both of the climate control (driver and passenger) side actuators were bad and the control unit that tells the actuators where they should be was also bad.
The truck was in the shop with most all the dash, seats, consol, and steering wheel out for a week. The cost was over $1200.00.
That has seamed to fix the problem. Good Luck.
